Although the enlarged body made some die-hard fans slightly unhappy, the series of models still won a lot of sales with their keen market sense. However, starting from this series of models, the main camera began to protrude from the surface of the fuselage, which also triggered complaints from many users. Some users even said that it was uglier than the wide injection molded strip on the back. Recently, Apple passed a new camera patent, which is expected to help Apple solve the problem of camera protrusion.
According to the latest listing published by the U.S. Trademark and Patent Office, Apple received patent number 3 for miniature high-resolution camera technology, which uses cutting-edge sensor technology with complex optics to create a compact, high-performance digital camera. According to the patent description, the photoelectric sensor adopts a spherical design to receive the light source, reflect it through a special lens array, and project it onto the concave surface. Think of it as a bowl filled with water. In this case comparison, the bowl represents the spherically curved image sensor, while the water represents the lens element.
In order to correct for diffraction and visual distortion, the lens array contains three lenses, two of which are convex lenses or generally convex lenses. The other one is a concave mirror, located between the previous two lenses and between the spherical photoelectric sensor. Such a lens array provides a relatively small camera module height and can produce sharper, low-distortion images. Source:
